Apple Mail
Highest reported open rate
75.86%

Open rates are inflated by Mail Privacy Protection. Use clicks, unsubscribes, and conversions to judge true engagement.

Other Providers
Highest bounce rate segment
3.16%

Smallest audience share but the closest list-quality monitor. Review bounces and suppress inactive addresses.

Sending Frequency
Actual campaign sends by month (11 campaigns, Jan 1 – Jun 15, 2026).

Sending comes in bursts: the ~8-week gap between February 4 and April 2, and no campaigns since June 15, interrupt engagement signals and make future inbox placement less predictable.

Key Deliverability Observations

  • Overall sender reputation is healthy. A 0.74% bounce rate and 0.02% spam complaint rate indicate no widespread deliverability issues.

  • Inconsistent historical sending is the main risk. Long gaps between campaigns can weaken subscriber familiarity and engagement signals.

  • Provider-level monitoring matters: Hotmail/Outlook has a higher bounce rate, Verizon has higher spam complaints, and Other providers have the highest bounce rate.

Overall Assessment

Current deliverability is healthy, with no major issues requiring immediate intervention. The main area to monitor is the impact of historically inconsistent sending frequency. As email activity becomes more regular, we will establish a clearer engagement baseline and track trends across major inbox providers.
